Abstract

Las espumas de polimero termoplastico expandidas y extruidas de baja densidad se obtienen utilizando un formiato de metilo sin VOC y sin HAP ambientalmente benigno como un agente de soplado, el agente de soplado puede ser una combinacion que incluye ademas al menos un co-agente de soplado, preferiblemente un espacie compatible con el medio ambiente (por ejemplo, sin VOC y/o sin HAP). El co-agente de soplado es ya sea un co-agente de coplado fisico (por ejemplo, un agente inorganico, un hidrocarburo, un hidrocarburo halogenado, un hidrocarburo con grupo (s) funcional (es) polar (es), agua o cualquier combinacion de los mismos) o un co-agente de soplado quimico o combinaciones de los mismos. Al espuma de polimero termoplastico puede ser una espuma de polimero aromatico de alquenilo, por ejemplo una espuma de poliestireno. La combinacion de agente de soplado puede comprender cualquier combinacion de formiato de metilo y uno o mas co-agentes de soplado. Las combinaciones de agente de soplado basado en formiato de metilo producen espumas estables para varias aplicaciones que incluyen envases, sistemas de empaquetado, asi como tambien tableros aislantes y materiales de construccion. Tambien se proporciona un proceso para la preparacion de estas espumas.
